In recent years, a concerted effort has been made to build up and delineate a discipline of applied history. But there has been little discussion about what applied history is, how the discipline navigates a range of epistemological problems, and how applied history is distinct from other disciplines that use historical data and attend to matters of policy—particularly political science.
